Stewart was charged to conduct the guns through the defile; but the task was difficult, several carriages broke down, and Trant’s corps thus took the lead of Paget’s column, the march of which was impeded by the broken gun-carriages. Meanwhile the cavalry, under Cotton, were misled by the guides, and came, in broad daylight, upon Franceschi, who, with his flank resting upon a wood, garnished with infantry, boldly offered a battle that Cotton durst not, under such circumstances, accept. Thus, an hour’s delay, produced by a few trifling accidents, marred a combination that would have shorn Soult of a third of his infantry and all his light cavalry, for it is not to be supposed that, when Franceschi’s horsemen were cut off, and general Hill at Ovar, Mermet’s division could have escaped across the Douro. When sir Arthur Wellesley came up to Albergaria with Paget’s infantry, Franceschi was still in position, skirmishing with Trant’s corps, and evidently ignorant of what a force was advancing against him. Being immediately attacked, and his foot dislodged from the wood, he retreated along the road to Oliveira de Azemis, and was briskly pursued by the allied infantry; but, extricating himself valiantly from his perilous situation, he reached Oliveira without any serious loss; and continuing his march during the night, by Feria, joined Mermet the next morning at Grijon. Franceschi, in the course of the 10th, could see the whole of the English army, including the troops with Hill; and it may create surprise that he should pass so near the latter general without being attacked: but Hill was strictly obedient to his orders, which forbade him to act on the enemy’s rear; and those orders were wise and prudent, because the principle of operating with small bodies on the flanks and rear of an enemy is vicious; and, while the number of men on the left of the Douro was unknown, it would have been rash to interpose a single brigade between the advanced-guard and the main body of the French. General Hill was sent to Ovar, that the line of march might be eased, and the enemy’s attention distracted, and that a division of fresh soldiers might be at hand to follow the pursuit, so as to arrive on the bridge of Oporto pell mell with the flying enemy. The soldier-like retreat of Franceschi prevented the last object from being attained. General Paget’s division and the cavalry halted the night of the 10th at Oliveira; Sherbrooke’s division passed the Vouga later in the day, and remained in Albergaria. But the next morning the pursuit was renewed, and the men, marching strongly, came up with the enemy at Grijon, about eight o’clock in the morning. COMBAT OF GRIJON.
